摘要：
Aiming at the problems of low mechanical properties and poor-hydrophobicity of nanofiber membrane, thermoplastic polyurethane (TPU) nanofiber membrane was prepared by electrospinning, and the TPU/tefluororone amorphous fluoropolymer (Teflon AF) superhydrophobic nanofiber membrane was obtained by impregnating in Teflon AF solution. The influence of immersion concentration and dipping time on the hydrophobicity and mechanical properties of the nanofiber membranes were analyzed by scanning electron microscope, electronic universal tester, and video contact angle tensiometer. The results show that when the mass fraction of Teflon AF is increased to 6%, the water contact angle of the nanofiber membrane reaches 150°, and the oil contact angle becomes lower than 3°, showing a superhydrophobicity. The mechanical strength of the nanofiber membrane were not affected by the impregnation, and the modulus of elasticity displayed an increase to 5.09 Pa. The nanofiber membrane implies good potential application value in filter media and biomedical fields. © 2021, Periodical Agency of Journal of Textile Research. All right reserved.
